Self preservation and protection. Rosie’s motivation to become her brother’s flying monkey was understandable and was based on self-preservation. Like many other people who do a narcissist’s dirty work for them, she didn’t pay much, if any, attention to the impact of her actions. Her need to look after herself was far greater than her need to protect anyone else. Forming an alliance with the person who is perceived as the strongest member of a family or organisation is one reason people adopt this role. Telling tales, spreading misinformation, and using gaslighting techniques against anyone who dares to question the narcissist might just mean you get to keep your job and don’t find yourself on the receiving end of narcissistic rage.
